Biodiversity and Multifunctional Features of Lactic Acid Bacteria Isolated From Table Olive Biofilms

Conclusion Lactobacillus pentosus was the predominant species found at industrial scale in Spanish table olives biofilms, albeit certain genotypes of L. plantarum were also detected. At genotype level, biodiversity was higher in the Spanish-style table olive biofilms than in those of directly brined olives. The multivariate analysis based on technological and probiotic data showed that the main 16 genotypes obtained could be clustered in 3 great phenotypes, with some strains with potential application as multifunctional starters (especially L. pentosus Lp13 and LpG1 genotypes). Data obtained in the present study showed the selective environment that governs table olive biofilms, where not all LAB genotypes has the ability to adhere on and, as a result, the reduced biodiversity of its flora.
